MEDIUM 5.1

Published 2026-08-10 · Last modified 2026-08-12

The affected TP-Link Aginet devices do not properly validate symbolic links created on external USB storage devices. By placing a crafted symbolic link on supported storage media, an attacker may cause the system to resolve the link. Successful exploitation may allow unauthorized read access to sensitive files within the device filesystem.
